Step 1: Ingredients

Step 2: Preparing Molds

Coat molds with oil, to make it easier to take out chocolate later.
Melt the white chocolate with 1 tbsp of oil. Colour it with powder color.
Smudge with brush coloured chocolate in parts of mold where should it be. And made one layer of chocolate. Put it in the fridge to cool.
Repeat coating with chocolate and return to fridge.
It can be done only with white chocolate too

Step 3: Filling

In the meantime cook sweet cream, butter and toffees. Stir until all is connected. Leave it 20 minutes to cool.
If the density is not enough, you can add the cornstarch or butter.
Pour the filling into molds and over that the rest of melted chocolate.
Back to the cooling for couple of hours.
All this can be done only with white chocolate.
